I’ve had this Midas Blenny for well over two months but about a week ago I noticed some scrapes along one of its sides. I assumed it was from going in and out of the rocks and just watched for infection. But then this morning part of both front fins are completely torn up. Then later today I noticed a white lump at the top of the dorsal fin. Anyone know what could be wrong? I have an emerald crab and some hermit crabs that could be the problem?
